S-93406A407 Length 7/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments
• Enhanced load distribution due to the wide truss head design, reducing surface pressure and material stress
• Reliable thread forming capability creates strong, permanent threads in sheet metal without pre-tapping
• Optimized for sheet metal applications with No. 21 drill bit compatibility and 0.025" maximum drilling thickness
• Secure Phillips No. 2 drive ensures efficient installation with common tools while minimizing cam-out
• Full threading and pointed tip for faster penetration and consistent holding power along the entire length
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

These No. 10-12 thread tapping screws deliver exceptional performance in sheet metal fastening applications where vibration resistance and long-term reliability are critical. The 18-8 Stainless Steel composition provides excellent corrosion resistance, making them suitable for outdoor equipment, HVAC systems, and electronic enclosures exposed to moisture or chemicals. The thread forming technology (A/AB type) creates precise mating threads in parent material without generating chips, eliminating contamination risks in sensitive assemblies. The wide truss head design offers superior clamping force distribution, preventing pull-through in thin gauge materials while the Phillips drive ensures compatibility with standard installation tools. This combination addresses common industrial challenges including material fatigue, galvanic corrosion, and installation efficiency in high-volume manufacturing environments.

Specification Summary & Compliance

This tapping screw features a No. 10-12 thread with 0.19" diameter and 12 threads per inch, manufactured to standard inch system specifications. The fully threaded design with pointed tip ensures optimal engagement in sheet metal applications. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial markets and restricted substance requirements.
